Video of thunderstorm hitting rural San Diego County

Anatomy of a thunderstorm

The National Weather Service in Rancho Bernardo monitors a large number of automated cameras to keep track of storms and other phenomenon. On Thursday, the network, known as HPWREN, captured a time-lapse video of a thunderstorm shooting through Dulzura in East County. The storm, say forecasters, caused some flooding. This particular sequence was shot from Lyons Peak, over a three hour period starting at noon.
